Management of organic waste is a major dilemma for increasing nation. It generates unpleasant odors & helps rats, flies, bugs & mosquitoes multiply & spread diseases. As it decomposes, organic waste generates methane a gas that contributes automatically to global warming. Last year Daniel Hoornweg, Perinaz Bhada-Tata & Chris Kennedy predicted in an article in the magazine Nature that the global rate of solid waste generation is expected to triple by 2100. This is bad news because if the investment for solid waste management in developing countries remains as low as it is today the world is at risk of inevitable ecological deterioration. Organic waste Composter organic waste for use as a resource is a missed convenience for some developing countries since 64 % of the waste generated in low income countries is organic according to the What a Waste report. There is remarkable incentive for developing nation to turn organic waste into a resource. The assistance for the atmosphere is huge & this could be done in a cost effective way. For example, organic waste could be turned into compost to grow crops, reducing addiction on chemical fertilizers or clean organic waste could be used to feed animals.
Decision makers in some developing countries are already productively implementing policies & providing incentives to reduce the quantity of waste going to landfills. The municipality of Ningbo (China), for example, generates about 3,300 tons of waste per day overwhelming its two landfills & two incineration plants. Responding to this crisis the municipality in partnership with the World Bank is implementing the Ningbo Municipal Organic Waste Composter Minimization & Recycling venture which will allow the municipality to achieve technologies & equipment necessary to support a latest program aiming to enhance the division of waste at source into four streams: recyclable, organic waste, hazardous waste & other waste. Separated organic waste will be processed into electricity & fertilizer for crops. To increase participation, financial incentives are provided to community groups for proper separation of waste into the four streams. We hope this will lead to an amplify in waste separation & encourage communities to be more aware & act to reap its benefits.
Similarly the State of Penang (Malaysia) adopted a policy in 2012 aiming to divert as much organic waste as possible from its landfill. Following this latest policy, local private segment entrepreneurs are responding by increasing latest technologies to turn organic waste into manure & generate income. Developed countries are also trying to address organic waste management issues. The state of Massachusetts has recently passed a latest regulation banning commercial organic waste from landfills in an effort to reduce the quantity of waste disposed into landfills. The rationale for banning commercial organic waste in Massachusetts is driven by the increasing quantity of waste generated in this small & densely populated state where landfill capacity is limited & disposal costs are high. Massachusetts became the first US state to impose such a ban, and we hope other US states will follow. We should not underestimate the value that is in our trash. With fast growth in waste quantity & soaring constraints in resources we have to become creative in how we transform our trash into a valuable resource. Organic waste which generally makes mainly of the trash that we discard can be managed in a smarter way.
